SPECIFICATION forming part of Letters Patent No. 442,119, dated December9, 1890.

Application led February 13, 1890. Serial No. 340,365. (No model.)

To a/ZZ whom `t may concern:

i Be it known that I, PATRICK K. HUGHES, a citizen of the United States,residing at @Wilkes-Barr, in the county of Luzerne and State ofPennsylvania, have `invented-a new and useful Machine for Turning Axles,of which the following is aspecification.

`.This invention relates to machines for turn ing or trimming thespindles upon carriage or Wagon axles; and it has for its object toconstruct a machine of this class which shall be simple, durable, andefficient, and which Shall be provided With a set or gang ofturning-tools, so as to be capable of operating simultaneously upon anumber of axles.

With these ends in view the invention consists in the improvedconstruction, arrangement, and combination of parts, which will behereinafter fully described, and particularly pointed out in the claims.

In the drawings hereto annexed, Figure 1 is a perspective vieW of anaxle-trimmin g machine embodying my improvements. Fig. 2 is a plan Viewof the same. Fig. 3 is a side elevation. Fig. 4 is a section of one ofthe chucks for the purpose of showing the construction more clearly.Fig. 5 is a detail view ofthe stop mechanism on one side of the machine.

Like numerals of reference indicate like parts in all the figures.

1 designates the bed or base of the machine, which is supported uponlegs 2 2. Boxes or bearings are provided at one end of thebase for aseries of longitudinally-arranged parallel tubular shafts 3 3, which arearranged in pairs, as shown, and are provided with gear- Wheels 4 neartheir front and rear ends adj acent to the boxes or bearings in whichthe shafts are mounted.

lntermediately between the shafts 3 3 are placed the longitudinal shafts5, having pinions 6, that mesh With the gear-Wheels upon the saidtubular shafts. The shaft-s 5 are provided at their rear ends with bandwheels or pulleys 7 to receive motion from some suitable source ofpower. The front ends of the tubular shafts carry the chucks 8, whichwill be presently more fully described.

9 designates a bed-plate, which is arranged to slide longitudinally uponthe base 1, and

which is provided at its ends with bearings for a shaft 10, arrangedtransversely to the the base and having a series of disks or toolholders11 equal in number to the number of 55 the tubular shafts 3, with whichthey-are in alignment.

Each of the tool-holders carries a series of turning-tools 12, the undersides of which have dovetailed ribs 13, adapted to engage 6c thedovetailed grooves 14, formed in the upper sides of the blocks "l5,which are mounted upon the base of the machine in front of the tubularshafts 3. i

The ends of the shaft are provided with 65 handles 1G, by means of whichit may be turned so as to place any desired set of tools 12 in alignmentWith the grooves 14, Where they will be centered to the chucks.

The chucks S are provided with radially- 7o movable slides 17, havingteeth 18, engaged by pinions 19, which are in turn engaged by Worms uponshafts 21, that extend through the rear sides of the chucks, where theyare provided with square posts or offsets 22, 75 adapted to be engagedby au ordinary key or Wrench, whereby they maybe turned so as to adj ustthe slides to or from the axles, which are thus held securely in thechucks.

The sliding bed-plate 9 is provided at its 8o edges WithdoWnWardly-extending flanges 23, having teeth 24:, meshing with pinions25, journaled upon the sides of the base. Said pinions 25 mesh withpinions 26, journaled upon short shafts or stubs 27, adjacent to the S5pinions 25, and having worm-Wheels 28 formed integrally therewith. Theworm-wheels 2S mesh with worms 30 upon the longitudinallyarrangedfeed-shafts 31, the rear ends of which are provided with pinions 32,connected by 9o intermediate idle-gears 33 with the pinions 4 upon therear ends of the tubular shafts 3, from which motion will thus betransmitted to the said feed-shafts. The Worms 30, which are mountedloosely upon the feed-shafts, have clutches 34E formed thereon, whichare adapted to be engaged by the clutch-collars 35, which are featheredor splined upon the shafts, and are provided with annular grooves 36,engaged by levers 37, which are pivoted to the sides roo of the base,and are provided with upwardlyextending arms 38, adapted to be moved byadj ust-able stops 39 upon the sides of the sliding bed-plate when thelatter reaches the limit of its movement.

The operation of this invention will be readily understood from theforegoing description, taken in connection with the drawings heretoannexed. The axles having been mounted in the chucks, the shaft l0 isadjusted so as to bring the desired set of tools into alignment with thechucks. The clutch-collars 35 are now thrown into engagement with theclutches 34, and the sliding bed-plate will then he moved slowly in thedirection ofthe chucks, the tools engaging and trimming the spindles ofthe axles mounted in the latter. When the stops 439 strike the levers38, the feed mechanism is thrown out of gear, and the sliding bed-platemay then be returned to its l original position and the shaft :10 bemanip-n- .lated so as to Iexpose an other set of tools,

Having thus described my invention, I claim and desire to secure' byLetters Patent of the United States l. In a machine for trimming axles,the combination of a 'series of tubular shafts having chucks at their.front ends, the supporting-blocks arranged in front ofthe same andhaving dovetailed grooves in their upper sides, a longitudinallyslidingbed-plate, a transverse horizontal shaftjournaled in suitablebear.ingsupon the latter, a series of disks i or tooLholders mountedupon said shaft in;l

alignment with the chucks and having the radially-arranged tools, andfeed mechanism geared from the said tubular shafts to the said g slidingbed-plate, substantially as set forth.

2. In a machine for trimming axles, the combination of a series oftubular shafts having chucks at their front ends, the supporting-blocks,the longitudinally-sliding bedplate having the transverse horizontalshaft carrying the tool-holders, provided Awith the radially-extendingturning-tools, the toothed anges extending downwardly from said bed-Aplate and meshing with gear-wheels upon the sides ofthe base of themachine, the pinions meshing with said gear-wheels and havingworm-wheels formed thereon, the .longitudinally-arranged feed-shaftshaving worms mounted loosely thereon and provided with clutches, theclutchcollars feathered upon said shafts, the .levers engaging said'clutch- 'j collars, the pinions at the `rear ends of the feed-shafts,and the .id legears oonnectingsaid pinions with geawwheels upon thetubular shafts, substantially as and for the purpose set forth.

In testimony that .I lclaim the foregoing as my own I have heretoaflixed my signature in presence of two witnesses.
